Abstract

Sliding operator assemblies and associated fenestration units, systems, and methods of use and assembly are described. Some such sliding operator assemblies transition a first, linear actuation force along a first axis (e.g., vertical) to a second actuation force along a second axis (e.g., horizontal) to cause a drive mechanism to impart opening and closing forces, respectively, on the sash. Some designs relate to belt-, twisted ribbon-, or band-drive sliding operator assemblies.
